GOOD TO KNOW

Common questions

What characters are changed?

Only printable ASCII characters from U+0021 (!) through U+007E (~) are changed.

Can I decode with the same action?

Yes. ROT47 is an involution, so running it again decodes the result.

Is this encryption?

No. ROT47 is obfuscation for text and is not suitable for protecting sensitive data.
